Are your online job postings attracting as many high-quality applicants as you'd like?
Do your online job postings provide salary information?
If the answer to both questions is "no," there's most definitely a connection. As an employer, I understand all the reasons why you don't list salary on your job postings. But the fact of the matter is, you're turning off a lot of job seekers by failing to include this information. Specifically, you're turning off the better job seekers, who won't bother to consider an opportunity unless they know the salary and it's acceptable.
